QuickerTek to ship charger
QuickerTek has announced a new External Battery Charger for Apple products with 30-pin connectors. The charger works with iPods using the aforementioned connector, the iPhone 3G and iPod touch. It expands the iPod's runtimes with up to 30 additional hours of music, six hours of video or three hours of talk time on the iPhone. The battery gets a charge through a retractable USB cable and it can charge an iPod as it is charged.
The charger uses 1800 mHa Lithium-ion battery and arrives with LED lights to indicate charging status. The new External Battery Charger will ship next week for $45.
